ABSTRACT:
A sewn attachment loop for a flexible rope used for rock-climbing, or working at heights, is formed by a short first portion of rope, securedly affixed to an extended second portion of rope by a seam. The seam presents a dissymmetric structure in the non-taut state allowing a homogeneous distribution of the mechanical stresses in the joining strands when the loop is tensed to the taut state. The stitches situated along the first portion of rope extend in the non-taut state of the rope according to a longitudinal staggering greater than that assigned to the stitches of the second portion of rope, the variation of the staggering of said stitches causing a progressive inclination of the joining strands along the seam.
